CREAM-SEPARATOR.

To all whom it may concern:

Be it known that I, AMANDUS" SroFiziD'S'rENBonu. of the city of Guelph, in the county of Wellington, in the. Province of Ontario, Canada, manufacturer, have invented certain new and useful Improvements in Cream-Separators, of'which the following is the specification.

My invention relates to improvements in cream separators, and the object oi'the invention is to provide a means of separating the skim milk from the cream, which will dispense with the use of tubes now commonly employed, and which will always insure of. a thorough separation an d it consists essentially of a bowl having a detachable top, a skimming shield 10-- -cated within the top and provided with holes or notches in its/bottom peripheral edge and a passage-way for the skim milk leading from the exterior of the shield through a rim formed on the-outsideconical-portion of the shield and the uppercylindricalportion to a' point above the top of the cap outside of the cylindrical portion, and a hole in the upper flange of the shield for the passage of the cream from the interior of the shield as hereinafter more particularly explained.

Figured, is a perspective view. oia cream separator constructed in accordance with my invention, portion being broken away and in section. Fig. 2, is a vertical section. Fig. 3, is a detail of the skimming shield.

In the drawings like letters. of reference indicate corresponding parts in each figure. I

A is the body of the bowl of a cream separator or other fluid separator,- which .may be of anysuitable form. p I 5 B is the detachable top or cover of the bowl, which tapers upwardly to a neck B and is provided with a p to. an exteriorly threaded flange on thetop of the bowl.

C is the skimming shield, which is provided at the bottom ith an exterior lateral outwardly extending flange Q and notches or holes C and an upwardlyextending flange 0 through which notches C descend.

D is a packing ring fitting between the flanges.

Specification of Letters Patent. Application filed March 21,1907- Ssrial No. $63,717.

Yatented Oct. 15, 1907.

The skimming shield is provided with a horizontal rim C, and 5. conical portion C? extending upwardly- 1 therefrom whereby a space is left between the skimming'shield and the cap and G is a rim iormed at the upper end of the conicalportion and forming a shoul-- der against which the cap abuts and fits.

C" arepassage-ways extending through the rim C and interiorly through bosses C projecting to the inside of the shield. The passage-ways C terminate at the top above the top of the caps is a holein the interior flange C forming part of the cylindrical portion of the skimming shield.

C is a rib located in proximity to the hole C.

The operation of my invention is'as follows. The skimmed milk passes upwardly around through the notches '0 and between the conical'portion of the skimming shield and the cap and onwardlythrough the passage-ways ,C and outwardly to the outside and entirely clear of the interior of the shield. The cream passes up throughthe 'hole- 0 It will thus beseen that the skim milk is entirely separated from the cream and thereis no liability of it coming in contact therewith as it'passes out from the separator on account oi the cream being carried upwardly through the hole C" to the inside of the skimming shield.

What I claim as my invention is:

The combination with'a centrifugal separator bowl having a tapered cap suitablysecured thereon. of n skimming shield having a tapered lower portion and a'-cylindrical upper portion and having the bottom rim resting on the upper edge'of thebowl. and provided with notches for the escape-of the skimmed milk and a horizontal rim and .a conical extending portion extending upwardly therefrom whereby a space is left hetween the cap and the skimming shield. and an annular rim and bosses formed in the shield on the interior thereof, and passage-ways extending outside of the shield through the rim and bosses to a point
